Want to cast your smartphone to your LG TV? This post shows you how to cast to LG TV from Android and iOS devices in 5 different workarounds.

Cast to LG TV via DIAL

LG Smart TVs (NetCast 3.0, NetCast 4.0, NetCast 4.5) come with DIAL (Discovery and Launch). DIAL allows you to cast content from some apps (like YouTube and Netflix) directly from a mobile device to an LG Smart TV without any external device.
